Problems solved by technology

[0002] The DC centralized lighting technology is to centrally place the distributed AC / DC rectifiers in the traditional LED lamp driver in the power supply cabinet, and use the voltage low-frequency rise and fall of high-voltage direct current to couple the dimming information, and transmit it to the decoding chip on the lamp driver for adjustment. A new type of dimming technology for light; the specific application method of DC centralized lighting technology is: low-voltage alternating current enters the power distribution cabinet, is transformed into 200V-300V DC by a rectifier module, and is output from the power distribution cabinet to the outside of the power distribution cabinet through multiple cables. However, the current industrialization of DC centralized lighting technology faces a pain point: the lack of a device that can quickly adjust the brightness of a lamp in a certain loop of the DC lighting power supply system
